- FIG. 10 is a schematic diagram of an internal structure of a portable beauty instrument according to an embodiment of this application.
- the portable beauty instrument includes a housing 10 , second electrodes 520 , third electrodes 530 , and a processing circuit L 1 .
- the housing 10 includes an end portion and a side portion that are used for contacting to-be-processed skin, an outer side surface of the end portion has a first region 010 and a second region 020 , and an area of the first region 010 is greater than an area of the second region 020 .

- the first electrode 510 extends in a first direction
- the second electrodes 520 and the third electrodes 530 are sequentially arranged in the first direction.
- the second electrodes 520 include a central electrode 520 a and several peripheral electrodes 520 b , and the several peripheral electrodes 520 b are disposed around the central electrode 520 a .
- the central electrode 520 a is a ring-shaped electrode
- the peripheral electrode 520 b is an arc segment-shaped electrode
- taking the central electrode 520 a as a center, the peripheral electrodes 520 b are distributed around the circumference of a specified circle at equal intervals.
- the peripheral electrodes 520 b of different sizes generate different degrees of stimulation. For example, if the diameter of the peripheral electrode 520 b is relatively small, a part of the peripheral electrode 520 b that is in contact with the skin is too small, and the user cannot feel electrical stimulation. If the diameter of the peripheral electrode 520 b is relatively large, a structure may also become large, a distance between the peripheral electrodes 520 b may also become difficult to maintain, and a local stimulation effect may also become poor. Therefore, the size of the peripheral electrode 520 b should be set properly according to an actual situation.
- the diameter of the central electrode 520 a may be from 8 mm to 12 mm, and the diameter of the peripheral electrode 520 b may be from 2 mm to 6 mm.
- the peripheral electrode 520 b in this application is in a shape of an arc segment. Compared with a plane electrode in the past, a contact area between an arc segment-shaped electrode and skin is larger, and a current easily invades skin of the human body. Because a current flowing in an arc shape easily reaches the inside of the skin, a current of the peripheral electrode 520 b can directly flow into the inside of the skin. That is, in this application, the peripheral electrode 520 b in a shape of an arc segment can effectively apply the current to the inside of the skin.
- a quantity of peripheral electrodes 520 b may be 4, 5, 6, or 8.

- the portable beauty instrument may further be provided with the first electrode 510 shown in FIG. 6 .
- the first electrode 510 is an arc-shaped electrode strip, and may be better attached to a concave facial region, especially in a concave part of nasolabial folds on the face. Therefore, an effect of lifting and tightening the skin is better.

All arc-shaped electrode strips may be negative electrodes or one thereof is a negative electrode. That is, each of the group-C electrodes 530 b may form a new electrode pair with an adjacent arc-shaped electrode strip, to generate a microcurrent.
- the second electrodes 520 occupy a relatively large range, and may act on a relatively flat large region, for example, a facial region, to improve working efficiency of the beauty instrument.
- the second electrodes 520 may generate a radio frequency current and a microcurrent, and send a soft electric wave to facial muscle, so as to stimulate vigor of the facial muscle, promote collagen regeneration, or stimulate the muscle, so as to tighten the skin.
- the third electrodes 530 occupy a relatively small range, and are triangularly distributed as a whole, and are more suitable for performing refinement work.
- the group-B electrodes 530 a in the third electrodes 530 work separately, and a microcurrent or a radio frequency current generated may act on a region such as the circumference of eyes.
- the first electrode 510 is an arc-shaped electrode strip. This design may enable the electrode strip to be better attached to the concave facial region, especially in a concave part of nasolabial folds on the face.
- the first electrode 510 may be combined with the group-C electrode 530 b in the third electrodes 530 to generate a microcurrent. By generating a low-frequency current deep into the skin to stimulate muscle movement in a concave facial region (especially in a mandible region), the muscle is contracted. Therefore, the first electrode 510 and the group-C electrode 530 b are mutually combined, and have a relatively good effect on skin lifting and tightening in the concave facial region.
- a plurality of electrode groups may be disposed at the same time in the beauty instrument. Different electrode groups may work independently or together, and there may be a plurality of different combination manners between the plurality of electrode groups, so that a microcurrent or a radio frequency current is generated by the electrode and acts on the skin, thereby stimulating the skin, and achieving an effect of lifting and tightening the skin and effectively resisting aging.
- a plurality of electrode groups may be disposed, either working independently or in combination, to have different processing manners for different skin parts.
- Working modes and output energy corresponding to different combinations of electrode groups are also different.
- the electrode is controlled to generate a microcurrent and a radio frequency current to stimulate the skin, so that the user can select radio frequency cosmetic or microcurrent cosmetic according to a condition of the user, so as to improve the skin, for example, implement at least one cosmetic effect of quick skin lifting, strong anti-aging, skin elasticity enhancement, 3-minute V-face contouring, and fading of nasolabial folds.

- Embodiments of this application relate to the field of electronic device technologies, and in particular, to a portable beauty instrument.
- With the advancement of technology and the progress of society, people are becoming increasingly concerned about skin care. While focusing on the effectiveness of skin care, there is also a growing emphasis on the overall experience of skin care. One of skin care manners is to process skin by using a portable beauty instrument with a radio frequency current or a microcurrent.

- To make the objectives, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely used to explain this application, but are not intended to limit this application.
- When a user uses a beauty instrument to beautify skin, the user needs to fully attach electrodes of the beauty instrument to a contact surface of the skin, so that the electrodes can discharge to stimulate the skin. To improve a cosmetic effect of a current on the skin, the electrodes are usually disposed in an end portion of the beauty instrument. When the beauty instrument needs to be used to beautify skin in a local target region with a small area, it is difficult to control a quantity of electrodes that are in contact with and discharge to the skin and a contact area. Consequently, the electrodes may act on irrelevant skin around the target region. In addition, for some biological parts located at the edge, for example, the ala nasi, it is difficult for the electrodes of the beauty instrument to be attached to the biological parts. As a result, some biological parts cannot be stimulated by the current of the beauty instrument. Therefore, this application provides the following embodiments to expand an area of a biological part to which a current of a beauty instrument radiates.
-
FIG. 1 is a schematic diagram of a structure of a portable beauty instrument according to an embodiment of this application.FIG. 2 is a side sectional view of a portable beauty instrument according to an embodiment of this application. - As shown in
FIG. 1 andFIG. 2 , the portable beauty instrument includes ahousing 10,electrodes 500, and a processing circuit L1. Thehousing 10 includes an end portion and a side portion that are used for contacting to-be-processed skin. Theelectrodes 500 are disposed in regions of the end portion and the side portion of thehousing 10, and are configured to discharge a current to stimulate the skin, thereby improving the skin. The processing circuit L1 is located in thehousing 10, and is connected to theelectrodes 500 to drive theelectrodes 500 to discharge. - The
electrodes 500 include afirst electrode 510,second electrodes 520, andthird electrodes 530. Thefirst electrode 510 is disposed in a connection region between the end portion and the side portion of thehousing 10, thesecond electrodes 520 are disposed in the end portion of thehousing 10, and thethird electrodes 530 are disposed in the end portion or the side portion of thehousing 10. Thethird electrode 530 may generate a radio frequency current or a microcurrent, and cooperate with thefirst electrode 510 to form a first electrode pair, to generate a current to stimulate the skin, thereby improving the skin. In addition, there are at least twosecond electrodes 520, and thesecond electrodes 520 cooperate to form a second electrode pair. The first electrode pair and the second electrode pair may separately discharge to the skin or simultaneously discharge to the skin. A user may adjust a mode of the beauty instrument to control a quantity of electrode pairs that discharge, thereby controlling cosmetic strength of the beauty instrument. - The
first electrode 510 and thesecond electrode 520 discharge currents to the skin, to expand a range of biological parts to which a current of the beauty instrument can radiate. For example, the user holds the side portion of the beauty instrument, and enables the end portion of the beauty instrument to come into contact with the skin, so that thesecond electrode 520 and thefirst electrode 510 can discharge to the skin by being attached to the skin. If the user wants to stimulate the ala nasi and surrounding biological parts, the user may tilt the beauty instrument, so that thefirst electrode 510 is attached to the ala nasi. For another example, if the user only wants to use the beauty instrument to process local skin with a relatively small area, the user may tilt the beauty instrument to attach thefirst electrode 510 to the skin to stimulate the local skin. - In an embodiment, there is an included angle of less than 120 degrees between the end portion and the side portion, and the connection region between the end portion and the side portion is a bent region between the end portion and the side portion. For example, there are two
first electrodes 510, the twofirst electrodes 510 are respectively located on two opposite sides of the end portion, and eachfirst electrode 510 extends along a bend line of the bent region, in other words, thefirst electrode 510 extends along the edge of the end portion, a part of eachfirst electrode 510 is located in the end portion, a part is located on the bend line, and a remaining part is located in the side portion. Certainly, if the bend line is ignored, it may alternatively be considered that a part of eachfirst electrode 510 is located in the end portion, and a remaining part is located in the side portion. For example, the included angle between the end portion and the side portion of the beauty instrument may be 110 degrees or 70 degrees. In this embodiment, the included angle between the end portion and the side portion is less than 120 degrees. When the beauty instrument is used to beautify some skin with a bending angle, for example, the ala nasi, the beauty instrument can be better attached to the skin of the part, to implement a tightening effect. - Certainly, in another embodiment, the
first electrode 510 may be a dot electrode, and does not necessarily extend along the bend line of the bent region. - In a process of using the beauty instrument, the
electrode 500 may generate a microcurrent, which acts on the skin and stimulates the skin, to lift and tighten the skin and effectively resist aging. Thefirst electrodes 510 have two arc-shaped electrode strips that are located in the connection region between the end portion and the side portion of thehousing 10. Because thefirst electrode 510 is an arc-shaped electrode strip, this design can make the electrode strip be better attached to facial contours, especially in a concave part of nasolabial folds on the face. Therefore, skin lifting and tightening effects are better. - In this embodiment, controlling the
electrode 500 to generate a microcurrent can stimulate the skin and improve the skin, for example, implement at least one effect of quick skin lifting, strong anti-aging, skin elasticity enhancement, 3-minute V-face contouring, fading of nasolabial folds, tightening of the circumference of eyes, strengthening of a skin barrier, and achieving smooth and radiant skin. -
FIG. 3 is a schematic diagram of an assembly manner of a first electrode of a portable beauty instrument according to an embodiment of this application. - Referring to
FIG. 3 , the portable beauty instrument includes afastener 512. The housing is provided with a through-hole in the connection region, and there is afastening portion 511 on a side of thefirst electrode 510 facing thehousing 10. Thefastener 512 is enabled to pass through the through-hole in thehousing 10 from the inside of thehousing 10 and connect to thefastening portion 511 of thefirst electrode 510, so that thefirst electrode 510 can be fastened to thehousing 10. - The
first electrode 510 is fastened in the following manner: A mounting position corresponding to thefirst electrode 510 in thehousing 10 is found, and thefastening portion 511 of thefirst electrode 510 is enabled to pass through the through-hole reserved on thehousing 10. Then, thefastening portion 511 that passes through the through-hole is found in thehousing 10, and thefastener 512 is mounted on thefastening portion 511, so that thefirst electrode 510 is fastened to thehousing 10. In this embodiment, thefastener 512 is disposed, and thefastener 512 is enabled to pass through the through-hole from the inside of thehousing 10 and be fastened to thefastening portion 511 of thefirst electrode 510, so that thefirst electrode 510 is fastened to thehousing 10, and thefirst electrode 510 can be stably fastened to a specified region without being shifted or loosened by an external force. - Optionally, a
sealing ring 1900 is sleeved on thefastening portion 511 or thefastener 512, to seal a gap between thefastening portion 511 and an inner wall of the through-hole or seal a gap between thefastener 512 and the inner wall of the through-hole. - Because contact between the
fastening portion 511 or thefastener 512 and the through-hole may be rigid contact, a deformation amount thereof may not be enough to block a gap between thefastening portion 511 or thefastener 512 and the through-hole that is caused by a machining error or the like. In this embodiment, thesealing ring 1900 is sleeved on thefastening portion 511 or thefastener 512, so that sealing and liquid penetration prevention performance of the beauty instrument can be enhanced. For example, thesealing ring 1900 can prevent a lotion, cosmetic gel, or the like from entering thehousing 10 from the gap between thefastening portion 511 and the inner wall of the through-hole or the gap between thefastener 512 and the inner wall of the through-hole. - Optionally, the
housing 10 is provided with a mounting groove in the connection region, a shape of the mounting groove is adapted to thefirst electrode 510, a groove depth of the mounting groove matches a height of thefirst electrode 510, thefirst electrode 510 is embedded in the mounting groove, the through-hole is disposed at a groove bottom of the mounting groove, and thesealing ring 1900 is located between thefirst electrode 510 and the groove bottom. - Because contact between the
first electrode 510 and the groove bottom may be rigid contact, a deformation amount thereof may not be enough to block a gap between thefirst electrode 510 and the groove bottom that is caused by a machining error or the like. In addition, when thefirst electrode 510 is in direct contact with the skin, the beauty instrument may be used together with some liquids (for example, a lotion or skin care gel), and the liquids may enter the beauty instrument through the gap between thefirst electrode 510 and the groove bottom, affecting performance of the beauty instrument. Therefore, disposing thesealing ring 1900 between thefirst electrode 510 and the groove bottom can enhance sealing and liquid penetration prevention performance of a region of the beauty instrument for contacting the skin. For example, thesealing ring 1900 can prevent a lotion, cosmetic gel, or the like from entering thehousing 10 from the gap between thefastening portion 511 and the inner wall of the through-hole or the gap between thefastener 512 and the inner wall of the through-hole. - Furthermore, in addition to preventing liquid penetration, the
sealing ring 1900 can enable thefirst electrode 510 to be better assembled into thehousing 10, so that thefirst electrode 510 does not move in a use process, thereby improving comfort of using the beauty instrument and facilitating use of the user. -

first electrode 510 is pluggable. Optionally, the user may unplug thefirst electrode 510, cover the end portion of the beauty instrument with a cleaning cloth/paper, and insert thefirst electrode 510 into a groove. In this way, the cleaning cloth/paper can be fastened on the end portion of the beauty instrument, and the user can clean the face by using the portable beauty instrument. - Optionally, in still another embodiment of this application, the portable beauty instrument includes a magnet.

FIG. 6 is a schematic diagram of electrode distribution of a portable beauty instrument according to an embodiment of this application; andFIG. 10 is a schematic diagram of an internal structure of a portable beauty instrument according to an embodiment of this application. - Referring to
FIG. 6 andFIG. 10 , in an embodiment, the portable beauty instrument includes ahousing 10,second electrodes 520,third electrodes 530, and a processing circuit L1. Thehousing 10 includes an end portion and a side portion that are used for contacting to-be-processed skin, an outer side surface of the end portion has afirst region 010 and asecond region 020, and an area of thefirst region 010 is greater than an area of thesecond region 020. Thesecond electrodes 520 are disposed in thefirst region 010, and thethird electrodes 530 are disposed in thesecond region 020. The processing circuit L1 is located in thehousing 10, and is connected to thesecond electrodes 520 and thethird electrodes 530. - For example, the
first electrode 510 extends in a first direction, and thesecond electrodes 520 and thethird electrodes 530 are sequentially arranged in the first direction. - The
second electrodes 520 include acentral electrode 520 a and severalperipheral electrodes 520 b, and the severalperipheral electrodes 520 b are disposed around thecentral electrode 520 a. Thecentral electrode 520 a is a ring-shaped electrode, theperipheral electrode 520 b is an arc segment-shaped electrode, and taking thecentral electrode 520 a as a center, theperipheral electrodes 520 b are distributed around the circumference of a specified circle at equal intervals. - Because the size of the
peripheral electrode 520 b affects interaction between the electrodes, theperipheral electrodes 520 b of different sizes generate different degrees of stimulation. For example, if the diameter of theperipheral electrode 520 b is relatively small, a part of theperipheral electrode 520 b that is in contact with the skin is too small, and the user cannot feel electrical stimulation. If the diameter of theperipheral electrode 520 b is relatively large, a structure may also become large, a distance between theperipheral electrodes 520 b may also become difficult to maintain, and a local stimulation effect may also become poor. Therefore, the size of theperipheral electrode 520 b should be set properly according to an actual situation. In this way, even if output power of theperipheral electrode 520 b is small, the user can easily feel it, which improves a cosmetic effect. In addition, even if power output of theperipheral electrode 520 b is suppressed, the user can obtain strong stimulation, and therefore, a power saving effect can be implemented. - For example, in some embodiments, the diameter of the
central electrode 520 a may be from 8 mm to 12 mm, and the diameter of theperipheral electrode 520 b may be from 2 mm to 6 mm. - The
peripheral electrode 520 b in this application is in a shape of an arc segment. Compared with a plane electrode in the past, a contact area between an arc segment-shaped electrode and skin is larger, and a current easily invades skin of the human body. Because a current flowing in an arc shape easily reaches the inside of the skin, a current of theperipheral electrode 520 b can directly flow into the inside of the skin. That is, in this application, theperipheral electrode 520 b in a shape of an arc segment can effectively apply the current to the inside of the skin. - In some embodiments, a quantity of
peripheral electrodes 520 b may be 4, 5, 6, or 8. Optionally, there are fiveperipheral electrodes 520 b in this application. - In some embodiments, the
third electrodes 530 may include group-B electrodes 530 a and group-C electrodes 530 b, where the group-B electrode 530 a in thethird electrodes 530 may generate a radio frequency current and a microcurrent as thesecond electrode 520. For example, thethird electrodes 530 are triangularly distributed as a whole. As shown inFIG. 6 , electrodes of the group-B electrodes 530 a are arranged at intervals in a length direction of thefirst electrode 510, electrodes of the group-C electrodes 530 b are respectively disposed on two sides of the group-B electrodes 530 a, and the group-C electrodes 530 b on two sides of the group-B electrodes 530 a are respectively close to one arc-shapedfirst electrode 510. Two electrodes of the group-C electrodes 530 b and one electrode of the group-B electrodes 530 a enclose another electrode of the group-B electrodes 530 a. - In some embodiments, the portable beauty instrument may further be provided with the
first electrode 510 shown inFIG. 6 . Thefirst electrode 510 is an arc-shaped electrode strip, and may be better attached to a concave facial region, especially in a concave part of nasolabial folds on the face. Therefore, an effect of lifting and tightening the skin is better. - In an embodiment, the
first electrodes 510 are separated by thethird electrodes 530, and/or are separated by thesecond electrodes 520. As shown inFIG. 1 , in a direction perpendicular to the first mountingplate 110, twofirst electrodes 510 are respectively located on two side edges of thehousing 10, thesecond electrodes 520 and thethird electrodes 530 are located between the twofirst electrodes 510, and in an extension direction of thefirst electrode 510, thesecond electrodes 520 are located at one end of thethird electrodes 530. - For example, the group-
C electrodes 530 b may work with the arc-shaped electrode strip of thefirst electrode 510, and all group-C electrodes 530 b may be positive electrodes or one thereof is a positive electrode. All arc-shaped electrode strips may be negative electrodes or one thereof is a negative electrode. That is, each of the group-C electrodes 530 b may form a new electrode pair with an adjacent arc-shaped electrode strip, to generate a microcurrent. - For example, the
second electrodes 520 occupy a relatively large range, and may act on a relatively flat large region, for example, a facial region, to improve working efficiency of the beauty instrument. Thesecond electrodes 520 may generate a radio frequency current and a microcurrent, and send a soft electric wave to facial muscle, so as to stimulate vigor of the facial muscle, promote collagen regeneration, or stimulate the muscle, so as to tighten the skin. Thethird electrodes 530 occupy a relatively small range, and are triangularly distributed as a whole, and are more suitable for performing refinement work. For example, the group-B electrodes 530 a in thethird electrodes 530 work separately, and a microcurrent or a radio frequency current generated may act on a region such as the circumference of eyes. However, thefirst electrode 510 is an arc-shaped electrode strip. This design may enable the electrode strip to be better attached to the concave facial region, especially in a concave part of nasolabial folds on the face. In addition, thefirst electrode 510 may be combined with the group-C electrode 530 b in thethird electrodes 530 to generate a microcurrent. By generating a low-frequency current deep into the skin to stimulate muscle movement in a concave facial region (especially in a mandible region), the muscle is contracted. Therefore, thefirst electrode 510 and the group-C electrode 530 b are mutually combined, and have a relatively good effect on skin lifting and tightening in the concave facial region. - With reference to the foregoing embodiments, a plurality of electrode groups may be disposed at the same time in the beauty instrument. Different electrode groups may work independently or together, and there may be a plurality of different combination manners between the plurality of electrode groups, so that a microcurrent or a radio frequency current is generated by the electrode and acts on the skin, thereby stimulating the skin, and achieving an effect of lifting and tightening the skin and effectively resisting aging.
- In this embodiment, a plurality of electrode groups may be disposed, either working independently or in combination, to have different processing manners for different skin parts. Working modes and output energy corresponding to different combinations of electrode groups are also different. The electrode is controlled to generate a microcurrent and a radio frequency current to stimulate the skin, so that the user can select radio frequency cosmetic or microcurrent cosmetic according to a condition of the user, so as to improve the skin, for example, implement at least one cosmetic effect of quick skin lifting, strong anti-aging, skin elasticity enhancement, 3-minute V-face contouring, and fading of nasolabial folds. In addition, when the plurality of electrode groups work together, working efficiency of the beauty instrument can be further improved, thereby saving time for the user.

FIG. 1 ,FIG. 2 ,FIG. 4 , andFIG. 6 toFIG. 9 , in an embodiment, the portable beauty instrument includes an adapter board L0, where the adapter board L0 is located in thehousing 10 and is disposed near the end portion, the adapter board L0 has several connection terminals corresponding to thesecond electrodes 520 and thethird electrodes 530, the end portion has first through-holes 101 corresponding to thesecond electrodes 520 and thethird electrodes 530, thesecond electrodes 520 and thethird electrodes 530 are electrically connected to the several connection terminals by using the first through-holes 101, and the several connection terminals are connected to the processing circuit L1. - In this way, the first through-
holes 101 are located on the end portion of thehousing 10, thesecond electrodes 520 and thethird electrodes 530 are fastened to the end portion of the housing by using the first through-holes 101, and are connected to the processing circuit L1 by using the several connection terminals on the adapter board L0. - For example, several
first fasteners 201 have conductivity, and a second through-hole 102 is disposed at a position of a corresponding connection terminal of the adapter board L0. Thesecond electrodes 520 and thethird electrodes 530 havefirst fastening portions 301 on sides facing the adapter board L0. Thefirst fastener 201 passes through the second through-hole 102 from a side of the adapter board L0 facing away from thesecond electrodes 520 and thethird electrodes 530, and is fastened to thefirst fastening portion 301, so that thesecond electrodes 520 and thethird electrodes 530 are electrically connected to the adapter board L0. - The second through-
hole 102 is located on the adapter board L0, and thefirst fastener 201 passes through the second through-hole 102 from the side of the adapter board L0 facing away from thesecond electrodes 520 and thethird electrodes 530. Thefirst fastening portions 301 on the sides of thesecond electrodes 520 and thethird electrodes 530 facing the adapter board L0 are connected to thefirst fastener 201, so that thesecond electrodes 520 and thethird electrodes 530 are fastened to the adapter board L0, and thesecond electrodes 520 and thethird electrodes 530 are electrically connected to the adapter board L0. - Optionally, in another embodiment of this application, at least two electrodes in the
second electrodes 520 are electrically connected by using a connection line, and then the connection line is connected to the adapter board L0. In this way, the processing circuit L1 can reduce a connection operation between the electrode and the adapter board L0, and reduce processing difficulty. For example, allperipheral electrodes 520 b of thesecond electrodes 520 are connected by using a connection line and/or a connection ring and/or a connection piece, and then connected to a connection terminal of the adapter board L0. - Optionally, in another embodiment of this application, at least two electrodes in the
third electrodes 530 are electrically connected by using a connection line, and the connection line is connected to the processing circuit L1. - In another embodiment of this application, the portable beauty instrument includes several sealing rings (not shown in the figure). The first through-
hole 101 is a stepped hole, each electrode of thesecond electrodes 520 is shaped to match the stepped hole, and is inserted into the stepped hole from the outside of the end portion and abuts against the stepped hole, and a sealing ring is sleeved on thesecond electrode 520 to seal a gap between thesecond electrode 520 and the first through-hole 101. - In some embodiments, a shape of the sealing ring may be specifically disposed according to a shape of the first through-
hole 101. For example, if the shape of the first through-hole 101 is annular, the shape of the sealing ring may be correspondingly disposed as an O-type. - In some embodiments, the sealing ring may be of a rubber material. Because the rubber does not absorb water and is impervious to water, a sealing ring of the rubber material may block a relatively small gas or liquid channel that exists on an attached surface between the
second electrode 520 and the first through-hole 101, so as to prevent water from entering thehousing 10 through the gap between thesecond electrode 520 and the first through-hole 101, damaging a component such as a circuit board, and causing a failure of the beauty instrument to work normally. - Similarly, a sealing ring may be disposed on the
third electrode 530, so as to prevent water from entering the housing from a gap between thethird electrode 530 and the first through-hole 101. - The material of the sealing ring sleeved on the
third electrode 530 may be an ultraviolet waterproof adhesive. The ultraviolet waterproof adhesive has a high solidification speed, high adhesive strength, good sealing performance, excellent water resistance and cold and hot resistance, and is safe and non-toxic. Therefore, water, gel, or other impurities can be effectively prevented from entering the housing from the gap between thethird electrode 530 and the first through-hole 101, so that thethird electrode 530 has good waterproof performance. In addition, the sealing ring sleeved on thethird electrode 530 may also assist in fastening thethird electrode 530, thereby improving stability of a connection between thethird electrode 530 and the end portion. - It may be understood that the material of the sealing ring may alternatively be another material. A specific shape and material of the sealing ring are not strictly limited in this application.
